The purpose of this article is to contribute to the research on the sign effect, steeper discounting of gains compared to losses, by offering results from an experiment using a "double-delay" procedure on adolescents. Twenty-four 14-year-old schoolchildren completed a computer-based test consisting of choices of Smaller-Sooner (SS) and Larger-Later (LL) hypothetical monetary gains and losses. Within-subject comparison and analysis of the aggregated data were conducted. Current results were also examined in light of prior research with adult participants, and variations in behavioral patterns were identified. Although the sign effect appears to be more profound in adolescents compared to adults, the effect of immediacy persists regardless of the sign of the outcome, and zero discounting of losses is often the case, suggesting that the sign effect is driven largely by qualitative differences.
本文旨在通过对青少年进行“双延迟”实验,为收益的折扣率大于损失的折扣率这一“符号效应”的研究做出贡献。24 名 14 岁的在校学生完成了一项基于计算机的测试,其中包括对较小-即时(SS)和较大-延迟(LL)假设货币收益和损失的选择。进行了个体内比较和汇总数据分析。当前的结果还与先前对成年参与者的研究进行了比较,并确定了行为模式的变化。尽管符号效应在青少年中比在成年人中更为明显,但即时效应仍然存在,无论结果的符号如何,而且经常出现零损失折扣,这表明符号效应主要是由定性差异驱动的。
